| coelom | <biology, embryology> An internal fluid-filled body cavity (other than the gut) within an organism, it lies between the gut (derived from the endoderm) and the outer body wall (derived from the ectoderm) and is lined entirely with tissue derived from the mesoderm. It is formed from the mesoderm during embryonic development. It is found in triploblastic animals called coelomates. (09 Oct 1997) |

| coelomate | <embryology> A triploblastic organism which has an internal, fluid-filled body cavity which originated from the mesoderm during embryonic development. This cavity surrounds the gut, may contain various other organs, and is called a coelom. It differs from the pseudocoels of the pseudocoelomates because it is not derived from the blastocoel. The term is used to classify multicellular animals by developmental pattern. (09 Oct 1997) |
| coelomic metaplasia | Potential of coelomic epithelium to differentiate into several different histologic cell types. (05 Mar 2000) |
